Opinion of the Court
Justice Stevens delivered the opinion of the Court.
The Endangered Species Act of 1973 (ESA or Act), 87 Stat. 884, 16 U. S. C. § 1531 (1988 ed. and Supp. V), contains a variety of protections designed to save from extinction species that the Secretary of the Interior designates as endangered or threatened.

1 The Act defines the term "endangered species" to mean "any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insecta determined by the Secretary to constitute a pest whose protection under the provisions of this chapter would present an overwhelming and overriding risk to man." 16 U.
